Which two scents are the closest to identical?

Like the topic says. Out of all the scents you've tried in your time as a fragrance enthusiast, which two do you think come closest to actually being the same scent, either in terms of the note pyramid or the scent itself?

My picks, from my admittedly limited experience:

Mont Blanc Legend and Curve For Men. I'm giving MBL a full wearing today for the first time and I'm continually struck by the astounding similarity. The notes diverge quite a bit but still, this basically feels like the same fragrance to me.

Molinard's Teck and Juicy Couture's Dirty English. Sampled these side by side the other day and I honestly would not be able to tell them apart in a blind test. Though the two share more notes than MBL and Curve do, they're still not identical. Regardless, to my nose the same thing is going on here: these feel like carbon copies of each other.

Then there are the knock-offs everyone knows about - MJ Legend, Unforgivable et al - but though they are similar to their predecessors I personally would have no difficulty telling them apart (though admittedly Legend is quite a bit closer to New Haarlem than Unforgivable is to MI). Certainly I don't find them anywhere near as similar as MBL/Curve and Teck/DE.
